摘要
合成了一种钴盐催化剂,采用热分析方法研究了氯酸钠分解过程。该催化剂能显著降低氯酸钠分解温度,使氯酸钠分解从超过500℃降低到近250℃。催化剂、粘结剂、抑氯剂和氯酸钠按一定比例混合,压制得到了氯酸钠盐柱。通过扫描电镜表征了盐柱结构与各成分分布,利用气体检测方法研究了盐柱燃烧及放氧行为。比较了干法压制和湿法压制的成型方法以及各组分配比对盐柱结构和燃烧的影响。优化配比和压制工艺,制备了能在低温燃烧的无燃料便携式氯酸钠氧烛,其燃烧温度低于氯酸钠熔融温度,放氧速率可在0~5 L/min之间调节,氯气释放量低于0. 001 mg/L,达到了便携式氧烛对烛体体积小、产氧率高、燃烧外壳温度低的要求。
A cobalt salt catalyst was synthesized with the aim of decreasing the decomposition temperature of sodium chlorate. The composition,assembly structure and decomposition behaviors of oxygen candle were investigated by consiclering the influences of catalyst,solvent,binder,chlorine suppression agent and pressing process. Portable metal-free oxygen candle was fabricated using a comprehensive manufacturing process. The oxygen candle can burn at the temperature lower than the melt temperature of sodium chlorate,of which the releasing rate of oxygen is 0-5 L oxygen per minute and the release amount of chlorine is less than 0. 001 mg/L. Catalyst and pressing process are key factors for the manufacturing of low temperature combustible sodium chlorate oxygen candle.
